TheSouthern Railway (abbreviatedSR) is one of theeighteen zones ofIndian Railways. It is headquartered atChennai and operates across thestates ofTamil Nadu,Kerala,Karnataka ,Andhra Pradesh and theunion territory ofPuducherry. The origin of the Southern Railway can be traced back to theMadras Railway formed in 1845. Southern Railway was created on 14 April 1951 by merging three state railways, namely, theMadras and Southern Mahratta Railway, theSouth Indian Railway Company, and theMysore State Railway and became the first railway zone created in newly formed India. Southern Railway maintains about 5,081 km (3,157 mi) of railway lines and operates 727railway stations. It has the distinction of operating the first railway line inIndia, which opened for traffic from Redhills to Chindadripettai inMadras on 12 September 1836.[2]

The history of the Southern Railway can be traced back to theMadras Railway. In 1832, the proposal to construct the first railway line in India atMadras was made by theBritish.[3] In 1835, therailway track was constructed betweenLittle Mount andChintadripet inMadras and became operational in 1837.[4] TheMadras Railway was established later in 1845 and the construction on the first main line between Madras andArcot started in 1853, which became operational in 1856.[5] In 1908,Madras Railway merged withSouthern Mahratta Railway to form theMadras and Southern Mahratta Railway.[6][7]
In 1944, all the railway companies operating inBritish India were taken over by the Government.[8] PostIndependence, various re-grouping proposals were studied as there were 42 different railway systems. In December 1950, the Central Advisory Committee for Railways approved the plan for Indian Railways into six zonal systems and the Southern Railway zone was created on 14 April 1951 by merging three state railways, namely, theMadras and Southern Mahratta Railway, theSouth Indian Railway Company, and theMysore State Railway.[9]

Southern Railway zone covers the states ofTamil Nadu,Kerala,Puducherry and a small portion ofAndhra Pradesh.[9]Andaman and Nicobar will form part of the zone once the proposed new railway line betweenPort Blair andDiglipur becomes operational.[10]
